So which product would be the one to be used with Sendmail?

The easiest to intigrate.  I would really be interested in doing this.  We
use Sendmail + Mailscanner.  I get at least 10,000 messages every 3 days
that have to have bounces because of spammers trolling for email
addresses.

Thanks for any links
